Abstract

593,050. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., and LONG, D. P. May 4, 1945, No. 11440. Drawings to Specification. [Class 40 (iv)] In a circuit arrangement using a high-speed marker controlled uniselector operating in response to one or two digits and with staggered wipers driven over corresponding arcs in succession, if selection is to be made in response to two digits a test is made after receipt of the first to determine whether a movement to a preliminary contact position is necessary. The test circuit includes a steering relay which by its operation reoperates the dialling relay for receipt of the second digit. The embodiment described is identical with that described in Specification 593,049.
